Description

[0001]
[Industrial applications]
The present invention relates to a method for laminating a cloth material such as denim or canvas on a surface of a shell-shaped body made of a synthetic resin such as an ABS resin, and a shell-shaped body such as a suitcase structure obtained by the method.
[0002]
[Prior art]
A known method of manufacturing a shell-shaped body such as a suitcase structure body of this type is to laminate an ABS resin color film 12 while stretching the ABS resin 11 into a plate shape, and to form a concavo-convex pattern (emboss) on the surface by a rolling roller. A step of obtaining a plate-shaped molding material 13 by attaching the plate-shaped molding material 13 to a molding machine 14 with a clamp 15, and then the inside of the container 16 of the molding machine 14 is heated to about 150 ° C. by a heater (not shown). By doing so, a step of softening the plate-shaped molding material 13, a step of injecting compressed air into the container portion 16 when the material is softened and inflating the molding material 13 like a balloon, The mold 17 is raised by the hydraulic cylinder 18 and when the rise reaches a predetermined position, the inside of the container is evacuated and softened. A step of bringing the formed molding material 13 into close contact with the mold 17, a step of blowing cooling air to the molding material 13 after the contact to solidify the molding material 13, and lowering the mold 17 to remove the shell-shaped product that has been completely formed. The step of removing the mold from the mold is performed in the listed order, so that the suitcase structure 19 is obtained.
[0003]
[Problems to be solved by the invention]
The method of manufacturing a shell-shaped body such as a suitcase component described in the above-described conventional technique includes a step of injecting compressed air to inflate the molding material 13 like a balloon. There was a fatal problem that it was not suitable.
[0004]
The present invention provides a novel method for laminating a cloth material such as denim and canvas on the surface of a synthetic resin such as an ABS resin, which has never been proposed to solve the above-described problems. It is an object to provide a shell-shaped body such as a suitcase structure.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a method of laminating a cloth material such as denim or canvas on a surface of a synthetic resin such as an ABS resin according to the present invention, and a shell-shaped body such as a suitcase obtained by the method are made of a synthetic resin such as an ABS resin. The denim, canvas, and other fabrics are pressed against the surface while the sheet is stretched into a plate shape, and the back of the denim, canvas, and other fabrics are integrated into the surface of the synthetic resin such as ABS resin. A step of forming a molding material, a step of heating the above-mentioned plate-shaped molding material into a heating device such as an oven until it is appropriately soft, placing the above-mentioned softened molding material on a male mold and lowering a female mold and / or After placing the mold on the mold and lowering the male mold, the softened molding material is molded into a shell shape. After the molding, the female mold and / or the male mold is raised to complete the molding. It is characterized in that the forming step of removing the shell shaped article from the mold, to listed order.
[0006]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0007]
First, the ABS resin 1 is stretched into a plate shape, and at the same time, the plate-shaped molding material 3 is formed by pressing the denim cloth 2 on the surface.
At this time, since the surface of the ABS resin is very soft, it enters into the fine uneven space of the denim by rolling. In other words, the back surface of the denim fabric is in a highly adhered state in which it is cut into the front surface of the ABS resin and integrated.
[0008]
Thereafter, the plate-shaped molding material 3 is placed in an oven and heated to about 150 ° C. to soften.
[0009]
The soft molding material 3 is placed on the male mold 4 and the female mold 5 is lowered to form the soft molding material 3 into a shell shape. After the molding, the female mold 5 is raised to complete the molding of the shell shape. The object is removed from the mold, and the suitcase structure 6 is obtained.
[0010]
Thereafter, parts such as a conventional aluminum frame are attached to the suitcase component 6 to complete a one-sided body (not shown) of the suitcase.
[0011]
The present invention employs another synthetic resin in place of the above ABS resin, uses cloth materials such as canvas in addition to denim, uses a heating device other than an oven, and turns a female mold downward and a male mold upward. Can also be implemented.
[0012]
By the way, when implemented with canvas, it is difficult to stretch the canvas compared to denim, so there is a weak point that defective products easily break at the corners, so it is necessary to devise the male mold and product shape .
[0013]
In other words, the present invention is not limited to the above-described example, and those skilled in the art may implement various changes or modifications within the scope of the technical idea described in the claims. Is what you can do. The present invention naturally extends to these implementations.
[0014]
【The invention's effect】
The present invention does not require any step of injecting compressed air to inflate the molding material 13 like a balloon, as in the manufacturing method described in the above-mentioned conventional technology, and completely solves the above-mentioned problems. It has a significant effect that enables the full achievement of the intended purpose. Further, it has an excellent effect that a cloth material such as denim can be securely fixed to a synthetic resin such as an ABS resin without an adhesive. Furthermore, the shell-shaped body such as a suitcase structure body obtained by the method of the present invention is a cloth-finished product such as denim with good finish, which is unique and has a significant effect with high product value.
